Yep! Night and day over the 1705. I ran for one for years on my 1999.5, it was ok, but now I just installed the PHP tunes and it is literally night and day difference for the better., shifting, and power are immensely better. Eggs are very modest for the amount of power derived from the programming.


Best 300 $ ie spent on the truck.

I kept my 1705 tuner.....but now it's just to read a code if I ever pop one.
